first i want defense from all positions, so now I'll name 2 other qualities i like to see:

pg-shooting, speed

sg-shooting, athleticism and ability to finish

sf-shooting, athleticism and ability to finish

pf-rebounding, agility

c-strength, agility

i like bigs that are more then just stiffs who are tall. When bigs can slide their feet and gaurd guys or run the court it helps the whole team play better. Centers also need to be physical and able to hold ground so strength means a lot there.
